- Some components are still being refined (like the d-pad and overall weight)

- Deadzone on the analog sticks has been greatly reduced.

- Both sticks feature stiffer resistance.

- Thumbs bumping into each other is no longer an issue, the analog sticks are spaced farther apart.

- Analog sticks have a ridged concave top that prevent your thumbs from slipping off.

- Stuck with symmetrical design. (Edit) Writer suggests the assymetrical design would cause more dificulties to interact with the touchpad without unintentionally bumping into the left stick. (Not said by sony or the game devs)

- Touchpad is multi-touch, replaces start and select buttons.

- Ridge at the end of the triggers grasps at your fingers instead of letting them slide off.

- There is a small speaker above the ps button, below the touchpad.

- Lightbar works in conjunction with the ps4 eye to track your position and adjusts the split screen accordingly.

- Controller felt comfortable and sturdy.

- Got input from Bungie (and a bunch of first party studios) for designing the DS4, Bungie really wanted to make it a controller that worked great for fps games.

- Writer of the article says the controller is a big reason for gamers to be excited for the console.
